With marathon-running grew in popularity, the effect of long-distance running on plantar pressure has been more attractive. It has been proposed that long-distance running influences the deviation in the center of pressure (COP) during standing and the changes to plantar pressure during walking. The objective of this study was to observe the effects on the COP motion amplitude of static standing and the plantar pressure distribution of walking after long-distance running. The influence of a 10-km run on changes to plantar pressure was assessed during standing and walking. Plantar pressure was measured before and immediately after running. In the study, seven males and five females participated in barefoot tests of static standing and dynamic walking. In the static standing tests, COP was measured under the following four ordered conditions: (1) bipedal, eyes open, standing; (2) bipedal, eyes closed, standing; (3) unipedal, eyes open, standing and (4) unipedal, eyes closed, standing. Under each condition, the data was collected while a stable standing posture for 10 s. In the dynamic walking tests, the contact duration and plantar pressure were recorded. The standing tests results revealed no significant differences between males and females while slight differences before vs. after running. Running for a single time had no effect on COP deviation during standing. The walking tests results revealed an initial landing on the lateral heel. After landing on the lateral heel, the females quickly transferred to the medial heel. The movement of the pressure to the medial heel was slower in males than females. After running, the pressure of females was more inward, while that of males was more outward under the metatarsal zones in the propulsion phase.
随着马拉松运动的普及，长距离跑步对足底压力的影响变得更加引人注目。有人提出，长距离跑步会影响站立时的中心压力（COP）偏差以及行走时足底压力的变化。本研究旨在观察长距离跑步后对静态站立时 COP 运动幅度和行走时足底压力分布的影响。评估了 10 公里跑步对站立和行走时足底压力变化的影响。在跑步前后测量了足底压力。在研究中，7 名男性和 5 名女性参与了赤脚静态站立和动态行走测试。在静态站立测试中，COP 在以下四种有序条件下进行测量：（1）双脚，睁眼，站立；（2）双脚，闭眼，站立；（3）单脚，睁眼，站立；（4）单脚，闭眼，站立。在每种情况下，数据在稳定的站立姿势下收集 10 秒。在动态行走测试中，记录了接触持续时间和足底压力。站立测试结果显示，男性和女性之间没有显著差异，但跑步前后有轻微差异。单次跑步对站立时 COP 偏差没有影响。行走测试结果显示初始着地在外侧脚跟。外侧脚跟着地后，女性迅速转移到内侧脚跟。男性向内侧脚跟的压力转移速度比女性慢。跑步后，女性在推进阶段的跖骨区压力向内，而男性压力向外。
